Here's a handy little snippet if you're working on an app which requires headphones. It allows you to detect when users connect/remove a headset but also determine if there is a microphone or not, as not all hands free kits are created equal.
On your activity, add this little snippet to your onCreate().
01.public HeadsetPlugReceiver headsetPlugReceiver;02. 03. protected void onCreate(Bundle savedInstanceState) {04. super.onCreate(savedInstanceState);05. 06. headsetPlugReceiver = new HeadsetPlugReceiver();07. IntentFilter intentFilter = new IntentFilter();08. intentFilter.addAction("android.intent.action.HEADSET_PLUG");09. registerReceiver(headsetPlugReceiver, intentFilter);10. }By registering the listener/filter we bypass the need to specify it in the manifest file.
And then onDestroy(), remember to unregister it.
01.@Override02. protected void onDestroy() {03. if (headsetPlugReceiver != null) {04. unregisterReceiver(headsetPlugReceiver);05. headsetPlugReceiver = null;06. }07. 08. super.onDestroy();09. }That should be enough to manage the handler during the activity lifecycle.
Lastly, implement the receiver logic.
01.public class HeadsetPlugReceiver extends BroadcastReceiver {02. @Override03. public void onReceive(Context context, Intent intent) {04. if (!intent.getAction().equals(Intent.ACTION_HEADSET_PLUG)) {05. return;06. }07. 08. boolean connectedHeadphones = (intent.getIntExtra("state", 0) == 1);09. boolean connectedMicrophone = (intent.getIntExtra("microphone", 0) == 1) && connectedHeadphones;10. String headsetName = intent.getStringExtra("name");11. 12. // ...13. }14. }Now that we've got headphone and microphone detection working ...
SINGSTAR BATTAL BITCHES!
